Adv. 1. soonest - with the least delay; "the soonest I can arrive is 3 P.M."
My cousin complains all the time he can't get a job and have no idea why he's been unemployed for so long... then I asked him: What time have you woken up every morning? Well... 11:30 am... that's the soonest I can do it!
To be honest I am not quite sure if my text is OK... could someone proofread that for me?
